In many regions of the world, older, high-emitting vehicles account for a small percentage of the overall vehicle fleet but a disproportionately large share of total emissions. It is estimated that these vehicles may be responsible for more than 50% of particulate matter (PM) and black carbon (BC) emissions by 2020 (Yan et al., 2011).
Marine vessels are a large source of greenhouse gas and air pollutant emissions, including CO2, NOX, SOX, particulate matter and black carbon, which impact local air quality, human health, and the global climate.
The white marble domes of the Taj Mahal are iconic images of India that attract millions of visitors every year. Over the past several decades the outer marble surfaces of the Taj Mahal have begun to discolor with time and must be painstakingly cleaned every several years. Although it has been generally believed that the discoloration is in some way linked with poor air quality in the Agra region, the specific components of air pollution responsible have yet to be identified.
This study establishes a baseline inventory of the number, types, and approximate distribution of DG sets in use in the Kathmandu Valley of Nepal and estimates air pollution emissions, including black carbon, from these generators.
Recent studies have shown that black carbon, a component of particulate matter (PM), is the second most powerful climate warming pollutant after carbon dioxide (CO2), and international experts have linked it to cancer and other serious health problems.
The Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants (CCAC) has released a report, titled ‘Time to Act – To reduce short-lived climate pollutants (SLCPs).' The report details the causes and sources of SLCPs, and outlines the potential benefits of control measures.
This report explains how climate change and development in wildfire-prone areas are driving up the risks and costs of wildfires; points out why current policies and practices may be worsening the situation; highlights the many different impacts and costs of wildfires; and provides recommendations for what we can do to limit these costs.
Two US senators went public with this proposal to cut short-lived climate pollutants (SLCPs) which are currently responsible for 40 per cent or more of global warming. Introducing the Super Pollutants Act of 2014, senators Chris Murphy (Democrat, Connecticut) and Susan Collins (Republican, Maine) have called for establishing a task force to review specific policies and laws to reduce black carbon, methane, and high-global warming potential (GWP) hydrofluorocarbons (HFCs).
